The dynamics of tourism’s carbon footprint in Beijing,China

Abstract

Beijing is an important hub for global tourism, but the extent of tourism’s contribution to Beijing’s carbon footprint remains unclear. We integrated an environmentally extended multiregional input–output model and the tourism satellite account in a study to estimate the dynamics of Beijing’s tourism-related carbon footprint in the post-financial crisis period. Our findings indicate that from 2007 to 2012, whereas the carbon footprint of inbound tourists in Beijing steadily decreased, that of domestic tourists increased. The composition of carbon footprints for the consumption activities of inbound and domestic tourists differed substantially. We also traced the spatial distribution of carbon sources associated with tourism consumption in Beijing. In light of our findings, we offer recommendations to target the adoption of low-carbon consumption patterns by domestic tourists, and energy optimization of service suppliers by increasing energy use efficiency and the renewable energy ratio. In addition, we recommend that public and government should seek to lower energy costs and reduce carbon emissions throughout the life cycle of commodities. We conclude that the government and tourism authorities should actively promote carbon and wider environmental awareness, and that producers must seek to improve the efficiency of their energy use by reducing carbon emissions at source.     

加工贸易、FDI与中国国际收支不平衡

自1994年我国实行汇率并轨制度以来,中国国际收支一直面临着经常项目与资本和金融项目双顺差的结构,产生这种结构的原因是多方面的,本文从以加工贸易为主的贸易特征和由于对外资优惠而吸收的大规模外商直接投资(FDI)这两方面入手,分析他们对中国国际收支不平衡产生的影响。

The Basic Ways of Solving the Problems of Underlying Liabilities of China＇s Endowment Insurance

The supply of basic pension is seriously lacking, the personal accounts is operated with no money. This is a problem belonging to conversion cost in essence. This paper points out that the government should undertake the responsibility to solve the problem by using the increment method and stock method to repay the latent liability; then the government can enrich the personal accounts in response to the aging population crisis and the concussion brought by the endowment insurance system＇s conversion.

Fiscal policy independence in a European Monetary Union

Do plans for a monetary union in Europe call for limits on the freedom of the country members of the union to use fiscal policy? In order to provide a tentative answer, we simulate the IMF model MULTIMOD, given various shocks, in the case of a European Monetary Union consisting only of France and Germany. The results clearly indicate the possible value of allowing unfettered use of fiscal policy in both countries. The reasons lie partly in differences in the initial position of the two, partly in differences in their preferences. We also examine the change in the policy significance of the current account in the monetary union. Current account imbalances clearly cease to have the same significance in a monetary union; but they do not therefore become irrelevant.     

美国经常项目赤字的可持续性研究

近年来，美国巨额经常项目赤字和美元持续贬值引起了经济学界的强烈关注，一些经济学家发出了美元和国际货币体系崩溃的警告。在现行国际货币体系即以资产为本位的泛布雷顿森林体系下。中心国家美国和外围亚洲国家形成了双赢的局面。该体系与布雷顿森林体系相比具有更大的安全性和稳定性。美国能够承受更大规模的经常项目赤字，并由此获得了更为灵活的政策操作空间。在某种程度上．美国巨额经常项目赤字是其雄厚的金融和经济实力的体现。     

Robust Monetary Framework for China

I. Introduction China has made tremendous gains in terms of economic growth in the last 15 years, by inviting foreign direct investment and increasing manufacturing production and exports. The currency unification (devaluation of the official rate and unification of the official and market rates) in 1994 also contributed to the efficiency in the monetary and foreign exchange systems. China was not severely affected by the Asian currency crisis of 1997–1998, and instead China helped the regio…     

The Role of Retail Competition,Demographics and Account Retail Strategy as Drivers of Promotional Sensitivity

We study the determinants of sensitivity to the promotional activities of temporary price reductions, displays, and feature advertisements. Both the theoretical and empirical literatures on price promotions suggest that retailer competition and the demographic composition of the shopping population should be linked to response to temporary price cuts. However, datasets that span different market areas have not been used to study the role of retail competition in determining price sensitivity. Moreover, little is known about the determinants of display and feature response. Very little attention has been focused on retailer strategic decisions such as price format (EDLP vs. Hi-Lo) or size of stores. We assemble a unique dataset with all U.S. markets and all major retail grocery chains represented in order to investigate the role of retail competition, account retail strategy, and demographics in determining promotional response. Previous work has not simultaneously modeled response to price, display, and feature promotions, which we do in a Bayesian Hierarchical model. We also allow for retailers in the same market to have correlated sales response equations through a variance component specification. Our results indicate that retail strategic variables such as price format are the most important determinants of promotional response, followed by demographic variables. Surprisingly, we find that variables measuring the extent of retail competition are not important in explaining promotional response.     

利率政策、金融结构与资本跨国流动——基于拓展的利率平价模型

利率政策和金融结构对资本跨国流动的影响力较强。在引入交易成本变量和放松风险中性假定的前提下,利用拓展的利率平价模型分析利率政策和金融结构对资本跨国流动及汇率波动造成的影响进行分析,结果得出,中国利率政策的顺周期性、粘性和单向惯性特征尽管不会导致资本跨国流动的边界发生位移,但是会使汇率的不稳定性加剧,并且持续的时间延长;中国现有金融结构的金融交易效率低和交易风险大的特征会导致资本净流入量减少,因此汇率面临着持续的、较大的贬值压力。
